Answer:
= 50 Minutes
Whole Race Time : 2 Hour and 50 Minutes
Step-by-step explanation:
so 2 Hour = 
Race completed
we need to find what 1/4 Race = x Hours
so 200 divided by 4 because Race is done.
we need to find how long to finish the whole race also known as 
.
200 divided by 4 = 50
so Holden still need 50 Minutes to finish the race.

The interval notation if you need it is (-2, ♾)
Answer:
a. Identify the population of interest in this study.
- all the population of the country
b. Identify the sample for the study.
- 50 adults (the ones that were surveyed)
c. Identify the parameter of interest in the study.
- the parameter of interest is the people that believe that coffee shops are overpriced
d. Find and interpret a 95% confidence interval for the parameter of interest.
z score for a 95% confidence level = 1.96
margin of error (E) = z score x √{[0.4(1 - 0.4)] / 50} = 1.96 x 0.069282 = 0.13579
95% confidence level interval:
0.4 - 0.13579 = 0.26421
0.4 + 0.13579 = 0.53579
- 95% confidence interval (0.26421 , 0.53579)
